Elevator system

Abstract

An elevator system includes guide rails located in an elevator hoistway and a running device adapted to reciprocate along the guide rails, and the guide rails are tensioned guide ropes.

What is claimed is: 
     
         1 . An elevator system, comprising guide rails located in an elevator hoistway and a running device adapted to reciprocate along the guide rails,
 wherein the guide rails are tensioned guide ropes.   
     
     
         2 . The elevator system according to  claim 1 , wherein the running device is a car and/or a counterweight. 
     
     
         3 . The elevator system according to  claim 1 , wherein a running direction of the running device is a vertical direction or has an inclination angle of smaller than 15 degrees relative to the vertical direction. 
     
     
         4 . The elevator system according to  claim 1 , wherein the guide ropes are steel wire ropes or carbon fiber ropes. 
     
     
         5 . The elevator system according to  claim 1 , wherein the guide ropes have a diameter between 10 mm and 30 mm. 
     
     
         6 . The elevator system according to  claim 1 , wherein a top end of the guide rope is connected to a top wall of the hoistway through a first end-connection device, a bottom end of the guide rope is connected to a pit of the hoistway through a second end-connection device, and at least one of the first end-connection device and the second end-connection device is an end-connection device capable of adjusting a tensioning degree of the guide rope. 
     
     
         7 . The elevator system according to  claim 6 , wherein the end-connection device capable of adjusting the tensioning degree of the guide rope is a rope fastening connected to the pit, and the rope fastening tightens the guide rope through a spring or a hydraulic device. 
     
     
         8 . The elevator system according to  claim 1 , wherein guide shoes are installed at the running device, guide portions of the guide shoes have guide holes, and the guide holes are sleeved over the guide ropes. 
     
     
         9 . The elevator system according to  claim 8 , wherein the guide portion of the guide shoe has two semicircular halves, and the two semicircular halves are spliced to form the guide hole. 
     
     
         10 . The elevator system according to  claim 9 , wherein the two semicircular halves each have a shoe liner, and after the two semicircular halves are spliced, the shoe liner is located at an inner circumference of the guide hole.
